Metastatic peritoneal carcinoma

Peritoneal metastatic carcinoma is more common in clinics, and is caused by cancer cells metastasizing through the bloodstream or by direct peritoneal growth. It is usually secondary to cancers in the liver, stomach, colon, pancreas and ovary in the abdominal cavity, and malignant tumors in the peritoneum. It can also be secondary to tumors in the lung, brain, bone, nasopharynx, and melanoma of the skin.
